i need perform single synchronous http post call: create http post request data, connect server, send request, receive response, , close connection. important release all resources used call. now doing in java apache http client. how can scala dispatch library ? something should work (haven't tested though) import dispatch._, defaults._ import scala.concurrent.future import scala.concurrent.duration._ def postsync(path: string, params: map[string, any] = map.empty): either[java.lang.throwable, string] = { val r = url(path).post << params val future = http(r ok as.string).either await.result(future, 10.seconds) } (i'm using https://github.com/dispatch/reboot example) you explicitly wait result of future, either string or exception. and use like postsync("http://api.example.com/a/resource", map("param1" -> "foo") match { case right(res) => println(s"success! result $res") case left(e) =...

i have xml document built using following structure: <a> .... <b> <c> </c> <d> .... </d> </b> </a> <a> .... i parse xml document using c# , output document in b-nodes emptied, without losing b-node. creating following result: <a> ... <b /> </a> <a> ... can show me way this? linq xml make pretty simple: var doc = xdocument.load(...); var bs = doc.descendants("b").tolist(); foreach (var b in bs) { b.replacenodes(); } (use replaceall instead of replacenodes if want remove attributes within b nodes well.)

so have found few previous topics on how none of them made sense me. wondering if explain how edit , add following: { "users": { "account1": { "name": "username1", "id": "user1id", "shown": "do show" }, "acount2": { "name": "username2", "id": "userd2id", "shown": "do show" }, }, "selectedaccount": "account1", i wish add new account accounts 1 , 2. wish change selectedaccount's value. any appreciated. so i'm still needing this, doing: jsonobject jsonobj = new jsonobject(sb.tostring()); jsonobject profiles = jsonobj.getjsonobject("users"); jsonobject jsonattribute = new jsonobject(); jsonattribute.put("name", "username0"); jsonattribute.put("id", "user0id...

when last used ddms android studio tried open *.hprof file, whole screen changed blank. now screen blank. reinstall android studio, eclipse , of course sdk, no effect. can tell me how reapir it? thank you i had problem too, , arrived @ same way (trying open heap dump *.hprof file). resetting perspective not work. how fixed it: go .android folder in home directory there should monitor-workspace folder; move backup directory (or delete it) restart ddms

i'd move integer nearest 'divisible 4' number in c++, not if number divisible 4. here's best attempt, i'm sure suboptimal: offset = (offset & 3) ? (offset | 3) +1 : offset; there must surely fast way of doing doesn't include tertiary if statement? additional note: in case offset 32-bit int. offset = (offset + 3) & ~(decltype(offset))3; or #include <type_traits> // ... offset = (offset + 3) & ~static_cast<std::remove_reference<decltype(offset)>::type>(3); if need support possibility offset reference type, such size_t& . @baummitaugen. it seems work when offset wider int without type cast, offset = (offset + 3) & ~3; , uncertain whether or not mandated language standard. this algorithm can described in english "add 3 round down". the rounding down part done setting 2 least significant bits 0 binary arithmetics. unsetting of bits done applying binary , inverse bit pattern, i...
